A US Internet radio host was convicted Friday of threatening to assault and kill three judges who upheld a ban on handguns in Chicago, the US Justice Department said.

Hal Turner, 47, was arrested in June 2009 for an Internet posting that said of the three federal judges who had upheld Chicago’s handgun ban, “Let me be the first to say this plainly: These judges deserve to be killed.”

His post included photos of the three men, Chief Judge Frank Easterbrook and Judges Richard Posner and William Bauer, as well as their phone numbers and work addresses.

All three judges testified during his trial, which was held in New York after Chicago judges recused themselves.

Prior to the trial, it was disclosed that Turner was a well-paid informant for the Federal Bureau of Investigation (FBI), pulling in over $100,000 from the government in just five years time.
